Specification of Letters Patent.

Application filed November 3,1905- SerialNo-285L768.

To all whom, it may cancer-1t;-

Be itknown that I, DANIEL F. WHITCOMB,

a citizen of the United States, and a resident of Cleveland, in the county-of 'Ouy'ahoga and State of Ohio, have invented certain new and useful Improvements in Telephone-Directories, of which the following is aspecification.

My invention is an improvement in telephone-directories; and it consists in certain novel constructions and combinations of parts hereinafter describedand claimed.

Referring to the drawings forming apart hereof, Figure 1 is a front View of my improved directory. Fig. 2 is a similar view with the front disk removed and withone of the plates partially withdrawn. Fig. 3 is .a rear view with the rear disk-removed. Fig. 4; isa front view of one of the plates, and Fig. 5 is a central vertical section through a telephone-mouthpiece provided with my direcflanges a are secured front and rear disks (1 M, respectively.

A plurality of substantially sickle-shaped plates B are pivoted to the front disk a, as at I), the free edges 1) of the plates being shaped to conform with the periphery ofthe frame. Each of the plates .13 is provided with a recess b for receiving thesleeve and the mouthpiece, and the inner edge of the plates is formed upon the arc of a circle, hav ing the point of pivotal attachment as its center and with a radius equal to the distance from the said point to the opposite side of the recess. The plates are arranged in spaced relation with respect to each other and with each plate overlapping the preceding plate. The plates might be described as being substantially circular-shaped, having a central opening to receive the sleeve and the mouthpiece and having that segment of the plate removed comprised between the arc of a circle having the point of pivotal attachment as its center, with a radius equal to the distance from said point to the opposite side of the recess, and a line parallel with a radius drawn from the center of the central opening through the center of the point of pivotal attachment. By this construction the plate is free to swing in one direction upon its pivot in order that it may be partially Withdrawn from the frame. At the junction of the in- "ner edge b and-the outer edge b each of the plates is provided with an inwardly-,projecting lip b =forengaging the sleeve to limit the outward motion of the plate with respect thereto, and for convenience in manipulating the plates each of them is provided with an ear 1), upon which maybe placed an indexletter I), the ears being spaced apart from each other and arranged at regular intervals around the periphery-of the frame when the plates are in their normal position. Upon the front face of the plates B are placed the names of-the subscribers, as shown at b.

The plates maybe constructed of any suitable material, as paper or celluloid, and may be in number corresponding to the letters of the alphabet, or more or less, as may be desired.

In use my'directory being in place upon the mouthpiece is rotated thereon until the desired letter is at the right side. By means of the ear the plate may be partially withdrawn from the frame, thus bringing the names of the subscribers under that indexletter to view. Since the inner edge of each of the plates conforms to the aroof adeflnite circle, an outward pull on the ear belonging to that plate will have but slight tendency to move the adjacent plates, since there will be more or less friction between the inner edges thereof and the sleeve.

It will beevid'entlfrom the description that .my improved directory, While simply constructed, is yet very convenient, durable, and maybecheaply manufactured.

Having thus described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A telephone-directory comprising a frame composed of a sleeve for fitting over the mouthpiece and provided at either end with flanges, front and rear disks having openings I to receive the-sleeve and secured to the flanges, a plurality of substantially sickle: shaped name-plates between the'disks, hav

too

35 ring-shaped frame adapted to be rotatably circumference of the frame, and the inner edge to the arc of acircle having the point of pivotal attachment as its center, and a radius equal to the distance from the point of pivotal attachment to the opposite side of the recess, theeXtreme point of the plates having a lip for engaging the mouthpiece, and each of the plates being provided'with an ear projecting beyond the frame, the plates being in spaced relation and each plate overlapping the preceding plate.

3. A telephone-directory comprising a circular frame for fitting over the mouthpiece, a

. plurality of name-plates within the frame and pivoted thereto near the circumference thereof, each of the plates having an elongated recess for receiving the mouthpiece, whereby I the plates may be partially withdrawn from the frame, the plates being arranged in spaced relation and each plate overlapping the preceding plate, and means on each of the plates projecting beyond the circumference of the frame whereby to partially withdraw the plate.

4. A telephonedirectory comprising a mounted upon the mouthpiece, a plurality of substantially sickle-shaped name-plates pivoted within the frame near the outer circumference thereof, the point of the sickle-shaped plates being provided with a lip for engaging the frame to prevent withdrawal of the plate therefrom, the plates being arranged in spaced relation and each plate overlapping the pre ceding plate, and ears on the plates projecting beyond the peripheryof the frame, the

ears being spaced apart from each other and arranged at regular intervals around the frame.

5. A telephone-directory, comprising a frame having a central opening adapted to receive the mouthpiece and to be rotatable thereon, a plurality of name-plates having recesses normally registering with the opening of the frame, the edges of the plates being normally flush with the edges of the frame, means whereby to partially withdraw the plates from the frame, and means on the plates for engaging the frame to limit their outward motion with respect thereto.

6. A telephone-directory, comprising a frame having an opening adapted to receive the mouthpiece, a plurality of nameplates within the frame and having recesses normally registering with the opening in the frame, means whereby to partially withdraw the individual plates from the frame, and a means on the plates for engaging the frame to limit the outward motion of the plates with respect thereto.

7 A telephone directory, comprising a frame having a sleeve adapted to receive the mouthpiece, a plurality of name-plates within the frame and having openings to receive the sleeve, the edges of the plates being normally flush with the edges of the frame, means whereby to partially withdraw the individual plates from the frame, and means on the plates for engaging the sleeve to limit the motion of the plates with respect thereto.

8. A telephone directory, comprising a frame for attachment to the mouthpiece, a plurality of name-plates within the frame, the edges of the plates being normally flush with the edges of the frame, means whereby to partially withdraw the individual plates from the frame, and meanson the plates for engaging the frame to limit the movement of the plates with respect thereto.
